The general term we apply to ore extraction from the earth is mining, and mining technology or mining engineering are the disciplines under which mining is practiced. Need a link? You'll find one below to the Wikipedia post on mining. If your question is applied to the mechanics of mining, we have to locate and map deposits of mineral ores. Then sample and test them for concentration ("richness"). Then either dig a shaft or start removal of overburden to form a pit. We can drill to set charges, blast, and then send in men and equipment to remove the material and get it out to a place from which it can be routed to processing, either on site or at a remote location.
